Abstract
Globalwarming and ocean acidification are among the most important stressors for aquatic ecosystems in the future.To investigate their direct andindirect effects on a near-natural plankton community, a multiple-stressor approach is needed. Hence, we set up mesocosms in a full-factorialdesign to study the effects of both warming and high CO2 on a Baltic Sea autumn plankton community, concentrating on the impacts on microzooplankton(MZP). MZP abundance, biomass, and species composition were analysed over the course of the experiment. We observed thatwarming led to a reduced time-lag between the phytoplankton bloom and an MZP biomass maximum. MZP showed a significantly highergrowth rate and an earlier biomass peak in the warm treatments while the biomass maximum was not affected. Increased pCO2 did not resultin any significant effects on MZP biomass, growth rate, or species composition irrespective of the temperature, nor did we observe any significantinteractions betweenCO2 and temperature. Weattribute this to the high tolerance of this estuarine plankton community to fluctuations in pCO2,often resulting in CO2 concentrations higher than the predicted end-of-century concentration for open oceans. In contrast, warming can be expected to directly affect MZP and strengthen its coupling with phytoplankton by enhancing its grazing pressure.
